Okay, I just activated my 3G unlimited plan and it went through fine. I turned on cellular data. What I want to know is how do I know when I'm using 3G or WiFi? On my iPhone it shows 3G in the menu bar when it's being used. Is it the same on the iPad? Right now it shows bars and AT&T and next to it the airport symbol. Will it say 3G when it's being used? Thanks for your help!
